I am going to introduce Japanese Hokkaido Milk which is getting popular in Bangkok. Hokkaido Milk sells yogurt, banana pudding, traditionally processed milk that provides deep flavor and etc. Also, you can taste many kinds of yogurts and flavored milk including the hottest flavor, honey flavored milk.
Since there is no such store in Korea, I bought a sweet potato flavored milk and a yogurt, and they were successful~^^
I was surprised with the deep flavor of sweet potato>_< When you have a chance to drop by Siam Center, try this Hokkaido Milk!!~
